MIAFAWW Specification of Letters .latent Patented "Nov. to, that To all whom it may concern:

Be it known that I, Wrnman J. LINDSAY,

a subject oi the King of Great Britain and Ireland and the Isle oi Man, residing; in Philadellfliia, county of l' hiladelphia. State of Pennsylvania, have invented certain Improvements in Gas-Producers, oi which the following is a specification.

My invention relates to certain improvements in gas producers of the type in which the bodyot the producer rotates and the stirring or slicer bars are suspended from a fixed frame and extend into the body portion. v l One object of my invention is to provide means for rotating the stirring: or slicer bars being carried by the rotating casing.-

.A further object of the invention is to provide means-by which the stirring or slicer bars are held inthe position to which they are adjusted.

In the accompanying drawings the figure is a vertical sectional View of a gas producer illustrating, my invention.

Referringto ,the drawings, 1 is a base on which the gas producer is mounted.

'2 is a rotating body portion of the pro ducer. Y I

3 is an air pipe extending into the cone 4. The producer is sealed in the ordinary manner, as shown. f I

5 is a worm wheel on the body portion and meshingwith this wheel is a worm 6 on a drivingshaft 7 by which the body portion of the producer is rotated. Other driving mechanism may be used without departing rests upon a series of flanged wheels 8-.

mounted in bearings, as shown in Fig. l.

9, 9 are beams located at each side of the producer and. supported on these beams, independently of the producer, is a beam 10 which carries the stirringbars 11.

12 is the top section of the producer and this section is stopped; the portion 1.3 being less in height than the portion 14. in the portion 14. is a fuel opening and gas outlet. The joint between the rotating body 53 and the top section 12 is sealed, in the present instance by a water seal 15.

The above construction is fully set truth and described in the patent granted to Claude hi. Garland, No. 1,079,234, dated November 153, 1913.

lnthe present instance, there are two slicer bars arranged at one side of the transverse central line of the producer. The bars are arranged at dilierent distances from the center so tl at each of the bars, as the body portion rotates, will cut its own path in the coking coal. Each slicer bar has a curved lower section it and one of the bars has a greater curve than the other, consequently, it has a more extended sweep. Each slicer bar rotated the body portion rotates,

tl'icret'ore, the entire mass of the fuel bed is agitated and kept in motion as the body portion rotates. Each bar passes through an opening 1'? in the beam 10 and has a worm wheel 18 splined thereto so that the bar must turn with the worm wheel.

19 is a driven shaft having worms 20 which mesh with the worm wheels 18, so that, as the shaft 19 rotates, a rotary motion will be imparted to each of the slicer bars. In some instances a stationary bar may be mounted in the bearings 28 in the beam 10, and one of the other bars may be stationary and only one rotate, without departing from the spirit of the invention.

The shape of the lower end of the stirring bar may be varied according to circumstances. ln the present instance, each stirring bar has a longitudinal spline 2-1 adapted to receive a key secured to the worm wheel, so that the stirring bar can be Vertically adjusted to any point desired, but will always turn with the worm Wheel. In

order to hold the stirring bar in the position to which it adjusted, transverse grooves 22 are made in the stirring bar at a given distance apart and a two-part collar 23 having a rib on its inner surface is clamped to the stirriilg bar, the rib enteringany one of the grooves This collar is held between the upper end of the worm wheel 18 and a bearing 24 supported by standards on the. beam 10. The weight of the stir- It will be seen by the above construction that, as the body of the producer rotates, one or more of the stirring here also rotates around its own axis and cuts a path in the fuel bed. The paths may be arranged close together or far apart, according to the speed of rotation of the stirring bar and .where tWo bars are arranged to rotate, as in the drawing, then one bar willcut through the path of the other bar, completely stirring the fuel bed.

As stated above, one or all of the bars may be adjusted vertically so as to bring them in line, as shown in the drawing, or

out of line, as desired.

l. The combination in a gas producer, of arotating body portion; a' fixed top section having two openings therein spaced different distances from the center of rotation of the body portion; a fixed beam extending directly above the top section and independently supported; two stirring bars carried solely by the beam and extending through the openings in the top section, said'stirring bars being bent out of line; means for rotating each bar, said bars being vertically adjustable; and means for retaining the bars in the adjusted position.

2. The combination in a gas producer, of a rotating body portion; a fixed top section; a fixed beam. extending over the top section; a stirring bar mounted on the fixed beam and extending through the top section and into the body portion, the lower portion of the stirring bar projecting at one side of its center line; a gear Wheel through which the stirring bar extends; said stirring bar being splined; a key on the gear wheel entering the spline so that the stirring bar must turn with the gear Wheel; means for retaining the stirring bar in the position to which it is adjusted; and means for rotating the body portion of the gas producer.

3. The combination in a gas producer, of a rotating body portion; a fixed top section; a fixed beam extending over the top section; a bearing on the beam; a stirring bar extending through the beam and through the said bearing and having longitudinal spline; a driving wheelinounted on the beam and having a key engaging the spline so that the stirring bar will turn WILLIAM J.
